Building LLVM on PPC

Project Infrastructure LLVM Dev List Archives

Please don't be alarmed by the failed compiles on llvm-ppc-darwin. They are likely not your fault.

I'm trying to get a PPC build bot setup (arxan_bellini), and so far it's dying here:

Any thoughts (besides don't try to build on PowerPC)

I'm trying to build with gcc-4.2 to see if that helps...

This also seems to fail on x86_64 Darwin (in this exact way) if -DBUILD_SHARED_LIBS is true.

It would seem that’s not maintained… I’m still working through some build failures.

I had to set BUILD_SHARED_LIBS for PowerPC because the linker was failing to generate jumps > 16M

Still churning away, but there seem to be issues with LLVMJIT (required CodeGen in the CMakeLists.txt)

and also seem to be issues with llvm-objdump.

File bugs against build-scripts, cmake?
